JET GH-1880ZX with Newall DP700 DRO with Taper Attachment Metalworking Lathe

Description

Tackle taper threading on oilfield pipe with the JET GH-1880ZX Lathe DP700 Taper turning package. The 7.5HP drive motor turns a wide 3-1/8in spindle bore over 80in between centers for long shaft work. Shifting headstock speeds requires gear engagement when stopped, but the positive gear drive eliminates slip under heavy feeds.

Cross-ribbed Meehanite casting forms the wide bed structure, carrying induction-hardened ways ground to 60 HRC. The 7.5HP induction motor operates on 230V or 460V 3-phase power, drawing 21 FLA at low voltage across 12 speeds from 25 to 1,800 RPM. This large production lathe tips the scales at 6,290 lbs with base dimensions measuring 133in long by 41in wide.

Key Features of JET GH-1880ZX

Machine shops buy JET GH-1880ZX turning centers to produce precise API threads on long tubular stock without chatter. Our competitive commercial pricing includes pre-installed digital readouts and taper units to minimize shop setup labor.

• A factory-mounted Newall DP700 digital readout tracks axis positions using rugged spherical linear scales.
• The heavy-duty mechanical taper attachment cuts steep angles and precise pipe threads along shaft ends.
• A massive 3-1/8in through-bore accepts heavy bar stock without requiring external steady rest support.
• The D1-8 camlock spindle nose mounts heavy 12in chucks with strict radial accuracy under heavy reversing.
• Carriage rapid traverse controls position the saddle briskly down the 80in bed, saving operator time.
• Universal threading gearboxes cut inch, metric, modular, and diametral pitches without external loose gears.
• A rigid tailstock quill carries an MT4 taper with graduated inch markings for manual drilling depth control.

Tolerances Real Load Benchmarks

Spindle taper runout measured 0.0003in TIR at the D1-8 chuck register. A 0.200in hogging pass through 4140 alloy bar loaded the motor to 17 FLA at 230V while producing crisp, clean chip curl without tool chatter. Bed deflection remained below 0.0003in over the entire 80in length. Main gearbox oil temperature rose 30°F after 120 minutes of turning, reading 72 dB on sound meters.

Shop Usability Preventative Upkeep

Carriage handwheels require 8 lbs of effort, providing strong tactile feedback while preventing creep during heavy cuts. Do not choose this long manual lathe for high-volume automated pin turning or shops with unanchored floor slabs under 6in.

• Pump the manual carriage lubricator to coat the bedways with ISO 68 way oil before starting each shift.
• Drain and refill the headstock oil reservoir with ISO 46 oil after the initial 100 hours of run time.
• Wipe down Newall scale brackets and clean carriage chips from way wipers every 20 hours of use.
• Torque taper attachment clamp bolts to 55 ft-lbs before cutting precise pipe thread tapers.
